Zeiss EVO 15LS SEM

X-ray map generated using the Zeiss EVO 15LS. It shows the unusual preservation of a peculiar type of ancient fish called Palaeospondylus. The skeleton of the fish appears as red (phosphorus-rich), cemented by calcium-rich minerals (green) in silicon-rich (blue) surrounding rock.

Detectors

Energy dispersive X-ray (EDX) detector

Capable of recognising the presence of most elements except hydrogen, helium, lithium and beryllium. Boron is difficult to find unless very abundant.

Wavelength dispersive X-ray (WDX) detector

Used to create spectrum scans when the EDX detector cannot separate signals from different chemical elements, or if they are present in very low concentrations.

Cathodoluminescence detector

Can create images from light emitted by the sample. including red-green-blue colour images.
